Statistics for Classroom Language Assessment: Using Numbers Meaningfully

Large-scale language testing uses statistical information to account for the quality of an assessment system. In this reflection article, I explain how basic statistics can be used meaningfully in the context of classroom language assessment. The paper explores a series of statistical calculations that can be used to examine test scores and assessment decisions in the language classroom. Therefore, interpretations for criterion-referenced assessment underlie the paper. Finally, I discuss limitations and include recommendations for teachers to use statistics.
